one of my girls was making a ruckus tonight at bed time. She was furiously dust bathing and pecking like crazy into the sand/pdz/poop mix on my poop board below the roosts. It looked like she was trying to break up the dried poop and was eating it. It was so gross! I tried to stop her but she wouldn’t stop so I just closed up the coop and went inside. Any idea why she would be doing this?!
